Flowback water. After a fracturing treatment on a gas well, the pumping pressure is relieved and fracturing fluid, mixed with water from the rock formation, begins to flow back through the well casing to the wellhead. In treatment-and-reuse scenarios, this is the water that will serve as the basis for fracturing fluid for the next job.
